A Go move is played on the intersections of the lines.
This is different from what you are used to from other
games like chess and checkers. In the figure we show
you the first four moves of an
instruction game.
The moves are numbered to indicate the order in which
they were played. That's right, in Go the black player
moves first! Another legal move, hard to display in a
figure, is pass. When both players pass the game is finished.
